I did this few days ago but trashed the file, frustrated. The animations themselves were very easy to create but could not get a good sync between.It looks stupid if the rotor spins too slow or the crosshair too fast. I was so tired at that nightly moment, it felt like only Einstein could triplicate the rotor animation, delete first and last frame from each loop and sync that with slower animation of N.It's not hard in fact and You can use same letters. All You need to do is to edit the original crosshair and rotor blade into black and overlay the animations on the canvas in right position.

I'll do this after few other ones, not probably today got some other things to do also, but as soon as I can.

Here. The rotor could be still faster vs the Crosshair, but hope this qualifies.With a bigger source file (tried to google but they were different) could add something to the letters too like I recall You wanted.

A bit faster. Animations are already combined so the Crosshair will be also faster.
